A failure of any part in the braking system should result in the application of brakes.
. It must be provided suitable means for dissipating stored energy of the rotating parts.ELECTRICAL BRAKING
A Good braking system should satisfy following Conditions It should be quick & reliable.

.TYPES OF BRAKING Two types of braking system are possible Mechanical or Friction braking Electrical Braking
ELECTRICAL BRAKING
ADVANTAGES OF ELECTRICAL BRAKING OVER MECHANICAL BRAKING 1.Since Mechanical braking due to excessive wear on the brake blocks or brake lining .hence there is saving in cost.needs frequent and costly replacement but no such replacement is required in electrical braking .

5.Frequent adjustment is required in mechanical braking hence more maintenance cost as compared to electrical braking 3.In electrical braking a part of energy is returned to the supply there by saving in energy. 4.In electrical braking the heat produced during barking is not hramful
.2.By employing electrical braking the capacity of the system can be increased by way of higher speed and haulage of heavy load.This is not possible in case of Mechanical braking.
